Summary: Effects of different levels in rations on production
indexes were studied with two groups of HF cows (N=22) during 50 days of
dry period and with four groups of cows during 90 days of lactation.
Differences in milk production were highly significant (P<0.01), whereas in
percent of lactic fat were nonsignificant (P>0.05). Average daily body
weight loss in periods between the 3rd and the 20th and the 3rd and the
60th day after calving were: 0.94, 2.76, 2.0, 2.88 and 0.46, 0.84, 0.74 and
1.05 respectively. The highest milk production at lesser body weight loss
was found in cows fed low energy level in dry period and high energy level
during lactation. Milk production level and cows body weight after calving
had highly significant effect on cows body weight loss after calving
(r=0.551** and 0.571**). Correlations between body weight loss and glucose
and FFA were -0.258 and 0.318*.
Keywords: cow, body weight, milk production, lactation, glucose, FFA.
